HeraldFloor StandingCondensing Boilers

Herald Gas Fired Condensing BoilersThe Herald range of floor standing Condensing Boilers comprises 8 models with heat outputs ranging from 41 to 228kW at a system design of 50/30°C. All models have low NOx emissions and seasonal efficiencies of up to 96.7% (Part L, Gross CV).

Herald is particularly suitable as a replacement product for old atmospheric boilers, and can offer significant savings on energy usage and carbon emissions.

Fully modulating pre-mix burner with 5:1 turndownAll 8 Herald condensing boilers feature advanced gas/air ratio controlled combustion

technology. This technology automatically adjusts fan speed according to heat demand and

providing the optimum proportions of gas and air to enter the burner. The 5:1 turndown

feature ensures that fuel consumption is matched to heat load from 20% to full load. Herald

boilers can therefore achieve the following efficiency levels :• Net Efficiency (full load) – up to 97.1%• Net Efficiency (part load) – up to 110.0%• Seasonal Efficiency (Part L2 Gross CV) – up to 96.6%• Seasonal Efficiency (ErP / Ecodesign) – up to 95.0%

Models HCB46CE and HCB61CE have outputs of 41 and 59kW respectively and under the ErP

Directive require Energy labels. Both models have Energy label A, and when installed with class

VI or VIII controls package, will qualify for Energy label A+.

Stainless Steel Heat ExchangerAt the heart of the Herald Boiler is a robust, grade

316l stainless steel heat exchanger which provides

superior resistance to corrosion and is supported by

a 10-year warranty.

Herald Boilers8 models available

Low NOx EmissionsHerald Boilers have Low NOx emissions, ranging

from 32 to 40mg/kWh depending upon model, and

therefore comply with the latest ErP Regulations

dated September 2018.

SMART System ControlsMost condensing boilers on the market operate at similar levels of efficiency, with good system design and control being crucially important factors in ensuring that boiler operating efficiency matches expectations. A key feature of the Herald range is its integral Smart system controls, which include:

• Multi-coloured graphic display• Modulating pump control• Cascade management for up to 8 Herald boilers• Fault signal output to BMS with open protocol• Ability to programme Service company details into display – this information is displayed when a service becomes due• Indirect Hot Water Pasteurisation programme

New Build or Replacement projects• High Temperature Operation - Herald Boilers can operate at tempera-

tures of up to 88°C which makes them suitable for installation as replacements for traditional atmospheric boilers – consideration should be given to hydraulic separation where water quality cannot be guaranteed – we can provide Hydraulic Plate Separators as Ancillary items

• High Working Pressure – suitable for systems with up to 11 bar working pressure

• Compact Design / Small footprint – at just 394mm wide, Herald boilers will fit through a standard doorway and the low height (845 or 1080mm depending on model), provides installation flexibility where plant room height is restricted

Flue OptionsA range of flue options are available including traditional conventional flue or room sealed concentric or twin pipe and with flue runs of up to 60m.

Con-X-us™

Con-X-us App-based Control This ancillary option allows the user to have full control of the Herald Boiler(s) using hand-held devices such as smart phones or tablets. Please see Con-X-us product literature and YouTube video for more information

Pipework Header Assemblies for Herald BoilersMultiple Boiler installations have become popular in recent years with cascade control enabling the Boiler installation to maintain high efficiency levels across a wide range of heat demand periods. Built-in redundancy is also a further benefit, and ensures that heat and hot water is still provided in the event of component failure on a single boiler.

Pipework header assemblies’ are currently available for Herald boiler models HCB86, 116 and 146 and for any combi-nation from 1 to 4 boilers. They can also be provided for installations of greater than 4 boilers. For example, two 3-boiler assemblies can be provided for a 6-boiler installation.

Herald Boiler Pipework Header Assemblies are supplied in ‘kit form’ for final onsite installation and include the following components:• Flow and return pipework headers• Boiler inlet and outlet pipework• Gas manifold• Bolt sets• Gaskets• Gas pipe cap end• Flange blanking plates

Matched primary circulation pumps and Boiler expansion kits are also available as optional ancillaries
